com.google.protobuf.AbstractMessageLite<MessageType,BuilderType>
com.google.protobuf.GeneratedMessageLite<Expr,Expr.Builder>
com.google.type.Expr
All Implemented Interfaces:
com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, ExprOrBuilder
public final class Expr extends com.google.protobuf.GeneratedMessageLite<Expr,Expr.Builder> implements ExprOrBuilder
 Represents a textual expression in the Common Expression Language (CEL)
 syntax. CEL is a C-like expression language. The syntax and semantics of CEL
 are documented at https://github.com/google/cel-spec.

 Example (Comparison):

 title: "Summary size limit"
 description: "Determines if a summary is less than 100 chars"
 expression: "document.summary.size() < 100"

 Example (Equality):

 title: "Requestor is owner"
 description: "Determines if requestor is the document owner"
 expression: "document.owner == request.auth.claims.email"

 Example (Logic):

 title: "Public documents"
 description: "Determine whether the document should be publicly visible"
 expression: "document.type != 'private' && document.type != 'internal'"

 Example (Data Manipulation):

 title: "Notification string"
 description: "Create a notification string with a timestamp."
 expression: "'New message received at ' + string(document.create_time)"

 The exact variables and functions that may be referenced within an expression
 are determined by the service that evaluates it. See the service
 documentation for additional information.
